Hi guys,

My rear windshield wiper works - however when I go for spray I don't hear anything. I read the sticky on the valve getting clogged..all that stuff.

But I don't hear anything.. where is the actual pump located?

 

Have you checked to see if they nozzle itself is clogged?

My rear nozzle was clogged when I got my R53. Used a saftey pin and squirted it a few times and it cleared up.

 

the Haynes wiring diagrams reflect only one pump that connects to two relay units, one for front and one for rear.

The pump is physically located behind the wheel well liner ... find the fill point under the bonnet and you'll figure it out. The pump is connected directly to the reservoir.
